Competent conjure

This spell conjures a transparent goblin.

You must give him a weapon or he will be forced to do unarmed damage. His health is determined by rolling 2d6. If casted not in combat the conjure follows you normally if not commanded to stop. The conjure can carry items for you (up to 20lbs). He can speak in one word answers (yes, no, maybe).

When combat ends (if he was conjured during or before) he fades out of existence. When this spell ends you must go pick up any item(s) you gave the conjure or you will leave the item(s) behind. Each level casted above 3 the conjure lasts though 1 more combat instance.

 You must use a vial of human tears to cast this spell everything is consumed including the vial.
